Fix for RNA struct registration: the bpy_class_validate function would only check the immediate functions/properties of the pointer struct type, but not potential base structs. Now it first validates the base struct recursively before the actual properties of the registered class.

Does not have any effect for current registerable types (Operator, Menu, Panel, etc.), since none of those actually have a base struct, but will be required for future types with an actual hierarchy (custom nodes).
